,PENCIL-SHARPENER.

Specification forming part of Letters Patent No. 49,210, dated August 8,1865.

To all whom it may concern.'

Be it known that I, H. P. ANDREWS, of Cleveland, in the county otCuyahoga and State of Ohio, have invented a new and ImprovedPencil-Sharpener; and I do hereby declare th at the following is a full,clear, and exact description thereof, which will enable others skillediu the art to make and use the same, reference beinghad to theaccompanying drawings, forming a part of this specification, in which-Figure l represents a perspective view of this invention when open. Fig.2 is a transverse section of the same when closed. Fig. 3 :is aperspective view of the same.

Similar letters of reference indicate like parts.

This invention consistsin a pencil-Sharpener composed of two concavejaws, which are hinged to each other and to a sheath, and provided withprojecting tongues, which drop into a groove ofthe sheath in such amanner that when the two are turned up together they are held closed bythe groove in the sheath, and in this case they act precisely like apencil-sharpener of the ordinary construction; butit' they are turnedout, each jaw can be readily cleaned and sharpened, or one jaw can beremoved and replaced by another, whenever it should be vdesirable,without throwing away the whole instrument.

A represents a pencil-Sharpener, which is composed of two concavejaws B,B', that are hinged to each other and to a sheath, G, as clearly shownin Fig. 1 ofthe drawings.

Each of thejaws forms one-halt` of the pencil-Sharpener, and when thesame are closed up they form a pencil-Sharpener of the ordinaryconstruction.

Each of the jaws is provided with a tongue, oil a', projecting from itsrear edge, as clearly shown in the drawings, and when the jaws areclosed up these tongues drop into a groove, b, on the back of the sheathG, as shown particularly in Fig. 2 ot' the drawings. In this positionthe sheath G forms lthe handle ot' the peny cil-Sharpener, and the wholedevice can be conveniently carried in the pocket, or a cord can be drawnthrough the eyelet which forms the pivot ofthe hinge-joint, and it canbe hung up in su`ch a position that it can be conveniently reachedwhenever it is required.

WVhen thejaws are thrown open to the position shown in Fig. lof thedrawings they can be readily cleaned out, and, furthermore, thecutting-edge ot' each jaw can be easily reached and sharpened, and it'one ot the jaws should be worn out or broken it can be easily removedand replaced by a new one without regard to the other parts ot' theinstrument. j The sheath does not materially increase the bulk of thepencil-sharpener. The whole device can be made cheaply and with littleexj pense, and a'pencil-sharpener can thus be made which is effectiveand durable, and, moreover, a pencil-Sharpener constructed in the mannerabove described is particularly adapted to sharpening slate-pencils.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. Apencil-sharpener made with two hinged jaws, B B',and a sheath, C, substantially as and for the purpose set forth.

2. The groove b and tongues a a', in combination with the sheath andjaws, applied and operating substantially as and for the purposedescribed.
